How to set the temperature of central air conditioning
As the high temperatures in summer continue, the frequency of use of central air conditioners has increased significantly. How to set the temperature scientifically, which can not only ensure comfort but also save energy, has become a hot topic recently. The following is a compilation of hot content on central air conditioning temperature settings in the past 10 days across the Internet. It combines professional advice and user practice to provide you with a practical guide.
1. Scientific basis for central air conditioning temperature setting
According to the "Design Code for Heating, Ventilation and Air Conditioning of Civil Buildings", it is recommended that the air conditioning temperature be set at24-28℃, in winter it is recommended to set the18-22℃. This range can not only meet human body comfort needs, but also effectively reduce energy consumption.
| season | Recommended temperature | relative humidity | Energy saving effect |
|---|---|---|---|
| summer | 24-28℃ | 40%-60% | Each 1℃ increase can save 6%-8% of electricity. |
| winter | 18-22℃ | 30%-50% | Each 1°C lowering can save 5%-7% of electricity. |
2. Temperature setting suggestions in different scenarios
1.home environment: The recommended temperature is 26-28℃ for the bedroom (can be adjusted higher by 1-2℃ during sleep) and 24-26℃ for the living room. Rooms for the elderly and children can be appropriately raised by 0.5-1°C.
2.office space: The recommended temperature is 26±1℃ in the open office area and 25±1℃ in the conference room. Data shows that for every 1℃ temperature increase above the recommended value, employee work efficiency may drop by 2%-4%.
3.commercial space: Shopping malls/supermarkets recommend 26-27℃, restaurants 25-26℃, and movie theaters 24-25℃. It is necessary to pay attention to the impact of crowd density on perceived temperature.
| scene type | Daytime temperature | night temperature | Special tips |
|---|---|---|---|
| residential | 24-26℃ | 26-28℃ | The newborn’s room needs to be kept at a constant temperature |
| office | 25-27℃ | - | Avoid direct air blowing to the workstation |
| medical institution | 24-26℃ | 25-27℃ | Operating rooms require special temperature control |
3. Common misunderstandings and corrections in temperature setting
1.Misunderstanding 1: "The lower the temperature, the faster the cooling.": The cooling speed of the air conditioner has nothing to do with the set temperature. Blindly lowering it will only increase energy consumption.
2.Misunderstanding 2: "Maintaining a constant temperature saves the most energy": Appropriately allowing a 2-3°C fluctuation (such as raising the temperature when going out) will save more energy.
3.Misunderstanding 3: "The air outlet temperature represents the effect": The air outlet temperature is usually 10-12°C lower than the room temperature, which is normal.
| Misunderstanding description | scientific explanation | Correct approach |
|---|---|---|
| The air conditioner needs to be turned on at 16°C to cool down | Body temperature is affected by many factors such as humidity and air flow. | Comfortable at 26℃+reasonable wind speed |
| Frequent switching saves power | The instantaneous power at startup is 3-5 times the operating power | It’s more economical to keep running for short periods of time |
4. New Trends in Intelligent Temperature Control Technology
1.AI temperature control system: Automatically adjust the temperature curve through machine learning, saving 15%-30% energy compared with traditional methods.
2.Human body sensing technology: Infrared sensors automatically detect the distribution of people and achieve precise temperature control by zone.
3.Cloud platform remote control: Supports advance pre-cooling/preheating to avoid energy consumption peaks caused by centralized start and stop.
According to JD platform data, sales of central air conditioners with intelligent temperature control functions will increase by 67% year-on-year in 2023, becoming the main direction of consumption upgrades.
5. The impact of professional maintenance on temperature control
Regular maintenance can ensure the cooling efficiency of air conditioning:
- Clean the filter at least 2 times a year
- Professional in-depth maintenance every 3 years
- Refrigerant pressure testing should be included in annual inspections
Actual measurement data shows that a well-maintained central air-conditioning system can reduce energy consumption by 12%-18% compared with an unmaintained system at the same set temperature.
Conclusion:Scientifically setting the temperature of central air conditioning requires comprehensive consideration of comfort, health and economy. It is recommended that users establish personalized temperature management solutions based on actual usage scenarios and combined with intelligent control technology. At the same time, pay attention to regular maintenance to achieve the best use effect.
